2. Overview:
In this section, it shows the port parameters, such as COM Number, TX and RX FIFO level, Termination
Resistor, etc. The description of these parameters are as follows:
• Port Number and COM No.
You will need to set up all the ports of the board with the desired "COM number", which should not
conflict with other COM numbers in use.
• RX and TX FIFO
Rx FIFO Level
- Low - Disables FIFO, resulting in decreased latency, and low throughput.
- High - Results in high throughput, but with increased latency. (Default)
Tx FIFO Level
- Low - Disables FIFO (recommended when the attached serial device has a small buffer, or slow
transmission speed).
- High - Results in high throughput. (Default)
